Wildest AI motion transfer hack: upload any stickman fight animation → inject custom backgrounds + swap in your own characters → preserve the exact choreography frame-by-frame.
Technically, this is skeletal motion retargeting applied to 2D sprites. The AI extracts keyframe positions from the stickman rig, then maps them onto arbitrary character meshes while maintaining timing and spatial relationships.
Use case: indie game devs can prototype combat sequences with simple stick figures, then apply polished assets later without redoing animation work. Also works for meme generation if you want your dog fighting a cat with professional martial arts moves.
The underlying tech likely uses pose estimation + optical flow to track joint positions, then applies inverse kinematics to rig new characters. No manual keyframing needed.
